T0 ctZZ whom, it may concern:

Be it known that I, HOWARD A. BEHAM, a citizen of the United States, residing at Renfrow, in the county of Grant, Territoryof Oklahoma, have invented certainnew and useful Improvements in Plows, of which the following is a specification.

The present invention relates to agricultural implements, and more particularly to improvements in that type of cultivators which comprise an arched member having a gang of cultivator-teeth trailing from each end thereof.

The object of the invention is to provide a cultivator in which the frame is so designed that the weightflof the operator counteracts the tendency of the cultivating-shovels to dig deeply into the ground.

The invention also contemplates novel means for adjusting the cultivator-teeth both vertically and laterally, according to the conditions under which the device is operated.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result reference is to be had to the following description and accompanying drawings, in, Which Figure 1 is a pers ective view of the cultivator with the whee s removed. Fig. 2 is a side elevation of the cultivator. Fig. 3 is a top plan view of one of the gangs of cultivators, showing the method of attaching the same to the main frame. Fig. 4 is a vertical sectional view through a portion of the cultivator, showing the mounting of one of the sleeves to which the gangs of cultivators are secured. Fig. 5 is a detached perspective view of one of the brackets upon which the operating-levers are fulcrumed; and Fig. 6 is a perspective view of one of the operatinglevers, the handle portion being broken away. Fig. 7 is a detail perspective view of the arched portion of the transverse bar.

Corresponding and. like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 designates the axle, which is supported upon the wheels 2 and is arched at its central point, as seen at 3. A trans versely-disposed bar 4 is located at the forward end of the frame for the cultivator and is provided with an arched portion 5, corresponding to the arch upon the axle. The

upper portions of the two arches 5 and 3 are connected by a pair of beams 6, which converge toward the forward end of the frame and meet a short distance beyond the bar 4, where they terminate in the drafttongue 7. The third beam is 8 interposed between the two beams 6 and extends rearwardly beyond the arch 3 and forms a support for the seat 9. The upper portion of the arch 5 is provided upon its outer face with a projection 10, against which the-beams 6 fit, the said projection having a head which projects over the top of the said beams. the intermediate or third beam 8 fits against this projection 10 and is connected to a transverse member 11, which bears against the lower sides of the two beams 6. Oblique braces 12 connect an intermediate point in each of the beams 6 to the lower portion of the arches 3 and 5, and the forwardly-proj ecting portions of the beams 6 are also connected in a similar manner to the forward arch. In this manner the frame is braced, so that all the members are held in a fixed position with relation to each other, and an extremely rigid construction is obtained. Bars 13 project rearwardly from the opposite arms of the arch 3 and have their ends bent upwardly and connected by the crosspiece 14, which is secured to the rearwardlyprojecting portion of the intermediate beam 8 and cooperates with the same to support the seat 9. i A gang of cultivators 15 trails behind each end of the forward bar 4, and these cultivators'are connected to the bar 4 by a peculiar coupling, which enables them to be readily adjusted both vertically and laterally. The beams 16 upon which the cultivator-shovels are mounted are of the usual construction and meet at their forward end, where they are pivotally connected to a link member The forward end of 17, so that they can swing in a lateral direction. The link member 17 is in turn pivotally connected to the sleeve 18, which is slidably mounted upon the bar and can be moved both toward and away from the arched portion thereof. Lugs 19 project upwardly from opposite ends of the sleeve 18 and cooperate with a rod 20, having a spiral formation for adjusting the sleeve. This rod 20 is j-ournaled between the two arms of an inverted-U-shaped frame 21, secured to the bar 4. The outer end of the rod terminates in a crank-arm 22, by means of which the same can be readily turned when it is desired to move the sleeve 18. In the specific construction of the link member 17 it will be observed that the same consists, essentially, of two spaced plates, between which the forward end of the cultivator-gang is pivoted, and that opposite ends of the plate are formed with forward projections which engage with the pivot-pin 23, passing through an eye at the rear portion of the sleeve 18.

The cross-piece of the invertedUshaped frame 21 is formed with a series of openings 24, by means of which the hook member 25 is adjustably connected thereto. This hook member engages with one end of a spiral spring 26, having the opposite end thereof connected to the intermediate cultivatorbeam 16. This spring tends to prevent the cultivator-shovels from digging too deeply into the ground, and its connection to the U-shaped frame 21 is regulatedaccording to the position of the sleeve 18 upon the bar 4.

In order to place the operation of the cultivator completely under the control of the operator while the implement is in use, a lever 27 is provided upon each side of the main frame, by means of which each gang of cultivatinglades can be moved from side to side or lifted o'utof operative position, as desired. These levers are fulcrumed at an intermedate point upon brackets 28, projecting from opposite sides of the arched portion 3 of the axle, and have their forward ends loosely connected to the cultivator, while their rear ends extend back within easy reach of the person upon the seat 9. The three cultivating-beams 16 upon each side of the device have their rear portions connected by spaced cross-pieces 29, having their intermediate portions oined by an upright member 30, which passes through an elongated opening 31 in the end of the lever 27. It will thus be seen that a loose connection is obtained between the two members which enables the cultivator-teeth to be raised and lowered or moved to either side, according to the wish of the operator. By pushing the rear end of either of the levers 27 downwardly and securing it under a hook member 32 upon the end of the cross-piece 14 the gang of cultivators controlled by the said lever can be held out of operative position.

The brackets 28, upon which the levers 27 are fulcrumed, are preferably formed of a single strip of material and comprise a pair of outwardly-projecting members 33, which are slightly spaced, the inner ends of the said members being flared outwardly and embracing the sides of the arch 3, to which they are secured. The fulcrum member 34 itself has an approximately U shape, the free ends of the arms thereof passing upwardly between the spaced sides 33 of the bracket and being bent in opposite directions so as to embrace the opposite sides of the bracket. In this manner a slidable connection is obtained which enables the fulcrum member 34 to be moved either toward or away from the arch 3, as may be required, for the proper control of the cultivator-teeth.

The numeral 35 designates the doubletree, which is pivoted to the forwardly-projecting portions of the beams 6, and for-this purpose plates 36 are secured to opposite sides of the beams, the said plates spanning the space between the beams and forming a suitable bearing for the pivot-pin. Each end of the doubletree is connected indirectly to the cerresponding end of the bar 4 by means of a link 37, having the oppc site end thereof loosely connected to a clip 38, secured to the cross-bar of the inverted-U-shaped frame 21 and an end of the bar 4. In the preferred construction the clip 38 forms a continuation of a rod 39, which has its rear end secured to the axle 1. In this manner the draft is distributed partly through the two arches and the beams connecting the same and partly through the link 37 and red 39. A series of perforations 40 are formed in each of the links 37 the pivot-pin 41 passing through one of the lower perforations, while the re maining perforations constitute a means for attaching the draft-animals.

In the operation of the device the distance between the two gangs of cultivators is adjusted by turning the cranks 22 and moving the sleeves 18 to the desired position upon the bar 4. Any vertical adjustment of the cultivators can then be readily accomplished by manipulating the levers 27, and at the same time the cultivators can be moved from side to side, as desired. One of the essential features of the invention resides in the fact that the axle 1 is located at anintermediate point between the seat and the cultivators, whereby the tendency of the cultivating-shovels to dig deeply into the earth is counteracted by means of the weight of the operator and the wheels 2 caused to have a firm engagement with the ground.

Attention is directed to the fact that in the structure shown in the drawings the brackets 28 are vertically adjustable upon the sides of arch 3 and that the fulcrum members 34 can be locked in a fixed position upon the brackets by means of set-screws, which. are provided for that purpose.
